Hi All
Is there max concentration of COD, N and P that Sequencing Batch Reactors can handle?

It is a general question.

As told before limits, if any, are suggested only by other BAT whenever process efficiency and cost may suggest other approaches.

In theory no, you can adjust the design to handle just about any COD, N and P.
But practically this will be unwise as you may be wasting money.
It will depend on the actual parameters. If you give more details, maybe we can help out.

Yes but there are a lot of variables. For just BOD/COD removal look at your loadings and SBR size in terms of sludge age and F/M ratio. For N removal you need a longer sludge age and an Anoxic stage. For P removal you need an Anaerobic stage followed by Aerobic to promote PAOs.
